My Autopano Pro forum

Rico, I'm using the Win version of 1.4 and there is definitely a bug in the control points editor when working with full frame fisheye shots.
If Autopano gets the stitch right the first time, the spheres are fine. But if it misses - that's it, there's no way to add control points.
I have not had any program crashes, but obviously this bug need to be squashed.
I don't think the control point addition logic works in fisheye shots because of the completely different distortions between the two images. So you select a square that contains the same features but the general SHAPE of the features is so different that the program just can't find matching points. Your eye sees the similar points in the two images but the computer can't.
I think the only way to solve this is to include TWO ways of adding control points - the existing one for non-fisheye shots and the ability to add a particular point (as in PTGUI) and match that point between the two images.
Until this gets fixed, AP isn't a viable choice for professional sphere photography.
However, that being said, if you want to make spheres using non-fisheye images AP is the best there is.

I've noticed that APP can't add control points in some cases.  One example is when I used an 18mm lens (Sigma 18-200) on a 300D and used about f/11.   Some parts of the picture were slightly out of focus, some were not.  Edges were more distorted and the focus was softer than in the center.  APP could not add points even where there were notable similarities (e.g. a metal plate with eight hexagonal bolt heads, letters, etc) if that feature was in the center of one image and the edge of another.

Well, I wish Alexandre would take another look at this bug.... I just tried one more time and got the pizza wheel and no control points.  I had to force quit as App was not responding.  This is very frustrating as I went to great trouble to aquire these new images.  Again it only happens with my 15mm fisheye, full frame canon lens.   Thanks for your comments.

Here's the issue. I'm pretty sure it happens when trying to stitch a zenith or nadir with another picture. I have to do some more checking with the picture because the fisheye search algorithm only work between picture rotated with the same angle. If one is +90° and the other 0°, it doesn't find any cp. I will improve this part to so it will work in either case.

Alexandre,  I did another test.  I will give you a screen shot of the test.  I tried to add control points to 2 vertical 15mm Canon fisheye images.  It took several minutes for the spinning pizza wheel to stop and then added cp's on the left image correctly inside the selection box. (highest points on the horizon feature)  In the right image the corresponding numbered cp's were placed wildly outside my selection box with no logic whatsoever.... So the theory that the bug only appears  with nadir or zenith and another image at 90 degrees is incorrect....

This is a 360 QTVR but here also is a regular pano I extracted from the full sphere.  Thank you!

[Win XP, 1.4A2]
I have the same problem for the CP outisde of aera or inaccurate.
I shoot with a D80 (crop 1.525) and a Sigma 10-20mm@10.

I dont have screen capture at this time, but i it need, i can do it !

Alexandre,  I think I stumbled upon the problem with adding the control points...  I was preparing to send you some files to test and figured I better do 1 more test.  I chose different files from those I had the problem with and found that the control points added correctly.  Same lens(Canon 15mm full frame fisheye)

I then realized the only difference in the two sets of images is that I had bracketed the first set and then selected only the normal exposure set out of the bracketed series.  So the images loaded into APP had image numbers separated by 2, due to the bracketing.

See the 2 images in the above example, 3318 and 3321.  So anyway it appears that image sets that are composed of non-sequential image numbers throw the control point editor off... If you still need images to test, let me know.  Thanks
